What term describes a material that does not allow liquids to pass through?

• A. Permeable
• B. Impermeable
• C. Absorbent
• D. Porous

Answer: (B)

The main idea is whether liquids can pass through a material. If a material does not allow liquids to pass through, it is impermeable. Permeable materials have pathways or pores that let liquids flow through, like a filter or a thin fabric. A porous material has many small openings, which commonly enable liquid movement. An absorbent material soaks up liquid into its body, focusing on taking in liquid rather than blocking it. So when describing something that acts as a barrier to liquid flow, impermeable is the best fit.
